TECHNICAL FIELD

The present invention relates to a heteroaryl derivative. Specifically, the present invention relates to a 6-(isooxazolidine-2-yl)-N-phenylpyrimidine-4-amine derivative. More specifically, the present relates to the compound, stereoisomers thereof, hydrates thereof, or pharmaceutically acceptable salts thereof, a method for preparation of the same, and a pharmaceutical composition for preventing or treating cancer comprising the same as an effective component.

BACKGROUND ART

The occurrence of cancers is related to a number of environmental factors including chemical substances, radiation, virus, and changes of oncogenes, tumor suppressor genes, genes associated with apoptosis and DNA repair and the like. Recently, the molecular mechanism of cancers is to be understood, and thus, this makes a targeted anticancer therapy, which is a new therapy, become available. Targeted therapeutic agents are generally prepared to show an effect by targeting molecules that cancer cells characteristically have. The molecular targets are genes associated with signal transduction pathway of cancer cells, angiogenesis, cellular matrix, cell cycle regulator, apoptosis and the like. An important targeted therapeutic agent used in the current therapy includes signal transduction pathway inhibitors, including tyrosine kinase inhibitors, and angiogenesis inhibitors and the like. It has been found that a protein tyrosine kinase plays an important role in a number of malignant tumors. In particular, it is known that epidermal growth factor receptor (EGFR), which is a receptor tyrosine kinase of ErbB family, is abnormally activated in a number of epithelial cell tumors including non-small cell lung carcinoma (NSCLC), breast cancer, glioma, squamous cell carcinoma of head and neck, colorectal cancer, rectal adenocarcinoma, head and neck cancer, gastric cancer, and prostate cancer; and the activation of the above EGFR-tyrosine kinase causes a persistent cell proliferation, invasion of the surrounding tissue, remote metastasis, and angiogenesis, and increases a cell survival.

Specifically, the EGFR, which is one of tyrosine kinase receptors of ErbB family, is a transmembrane tyrosine kinase that has an extracellular ligand-binding domain and an intracellular domain including a tyrosine kinase domain, and may include EGFR (referred to as ErbB1 or HER1), HER2 (referred to as ErbB2 or neu), ErbB3, and ErbB4 (referred to as HER4). If a ligand binds to a receptor forming homodimer or heterodimer, a tyrosine kinase in a cell is activated, and a signal stimulated by EGFR as such activates phosphatidylinositol 3-kinase ((PI3K)/AKT/mTOR, RAS/RAF/MAPK, and JAK/STAT) signal transduction pathway (Non-patent Literature 0001). In particular, EGFR is overexpressed in at least a half of non-small cell lung cancer (NSCLC), and thus, a number of studies have been carried out in which EGFR is a target of a therapy. EGFR TKIs (tyrosine kinase inhibitors), which inhibit an activity of EGFR tyrosine kinase, have been developed, and representative drugs include Gefitinib (IRESSA™) erlotinib (TARCEVA™), and lapatinib (TYKERB™, TYVERB™).

On the other hand, it was reported that, in 2004, an activating mutation of EGFR is correlated with a response to gefitinib therapy in non-small cell lung cancer (NSCLC) (Non-patent Literature 0002 and 0003). Specifically, it is known that the above EGFR mutation is largely classified into a sensitizing mutation and a resistant mutation, and a deletion of exon 19 and a L858R point mutation of exon 21 are the most important sensitizing mutations and make up about 85 to 90 percent of a sensitizing mutation, and an exon 19 del mutation is more sensitizing to the TKI. On the other hand, it is known that a T790M point mutation of exon 20 is the most important resistant mutation and is found in at least 50 percent of acquired resistant patients (Non-patent Literature 0004).

Somatic mutations identified hitherto include an in-frame deletion in exon 19 or an insertion in exon 20, as well as, a point mutation in which a single nucleic acid residue is modified within an expressed protein (for example, L858R, G719S, G719C, G719A, L861Q) (Non-patent Literature 0005 to 0007).

Despite an early clinical effect of gefitinib/erlotinib in NSCLC patients with an EGFR mutation, a progressive cancerdevelops in most patients in the end while these patients are receiving a therapy of these drugs. In an early study of recurred samples, a secondary EGFR mutation, T790M, was identified, which made gefitinib and erlotinib to be ineffective inhibitors of EGFR kinase activity (Non-patent Literature 0008 to 0009). It has been proved in the follow-up study that the EGFR T790M mutation was found in approximately 50 percent (24/48) of tumors derived from patients who acquired a resistance against gefitinib or erlotinib (Non-patent Literature 0010 to 0012). The secondary genetic modification is caused in a position similar to a ‘gatekeeper’ residue and a secondary resistance allele associated with the same in patients to be treated with a kinase inhibitor (for example, T3151 within ABL in imatinib resistant CML).

It has been known for a long time that EGFR del19 or EGFR L858R, which is an EGFR mutation, is a major cause of non-small cell lung cancer and head and neck cancer, and IRESSA and TARCEVA, which are therapeutic drugs of the cancers, were developed and are currently used in clinical trials. However, when such drugs were administered for cancer patients, an acquired resistance caused by an EGFR secondary mutation based on the structure of the drug was observed. In addition, it was found that this was actually a major cause of drug resistance. If first generation inhibitors of EGFR have been used for about ten months in average, an acquired resistance, which is a T790M mutation positioned in a gatekeeper of EGFR kinase, occurs to prevent first generation inhibitors of EGFR exerting a medicinal effect. That is, EGFR del19 T790M or EGFR L858R T790M double mutation occurs to prevent conventional therapeutic agents exerting a medicinal effect.

<Experimental Example 1> Evaluation of Ba/F3 and Lung Cancer Cell Proliferation Suppression Activity

The following experiment was carried out to evaluate the suppression activity of the compounds according to the present invention against proliferation of Ba/F3 and lung cancer cells which express EGFR mutations.

Of the cancer cell lines expressing the EGFR gene, A549 was cultured after adding 10% FBS (HyClone) to DMEM (Invitrogen), and RPMI-1640 (Invitrogen) with 10% FBS was used for the other cancer cells. For the Ba/F3 cells, RPMI-1640 with 10% FBS and 5 ng/ml IL-3 (R&D Systems) was used. The transduced Ba/F3 cells were cultured by adding 1 ug/ml puromycin (Invitrogen) to the same medium.

24 hours before treatment with the compounds, 3000 to 5000 cells were distributed into each well of a white clear bottom 96 well plate (Corning). The compounds were diluted in dimethylsulfoxide (dilution ratio 3:1; 12 concentrations total) and injected 0.5 ul each for a final concentration of 0.3 nM to 50 um. As for measurement of live cells, 72 hours after treatment with the compounds, a CellTiter-Glo luminescent cell-viability reagent (Promega) was used to store the cells at room temperature for 10 minutes, followed by measurement of luminescence using a reader (SynergyNeo, Biotek). Each test was repeated three times.

The result was calculated as a cell growth ratio (%) compared to a control. The program GraphPad Prism version 5.0 was used to draw the graphs and calculate the GI₅₀ values.

Table 2 below shows the results of proliferation suppression for Ba/F3 cells which express EGFR (HER2) mutations.
